In this hydrated salt worksheet, young scholars answer questions after completing a lab experiment using a hydrated salt. The calculate the empirical formula for the hydrate, they name the hydrate and they determine the mass of the water...

In this water equilibria worksheet, students calculate the pH of solutions, they fill in a table with the type of acid or base given a compound and it's concentration and they calculate approximate solubilities for salts.

In this water worksheet, students are given the percent of distribution of water on earth. With the total amount of water equal to 1,000ml students determine the number of ml for each type of water on earth and color a beaker with the...

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Students manipulate Hudson River salt front data from October 2004 - September 2005 to locate the high and low points of the salt front for each month, They determine the range for each month, determine the modal range for each month,...

Students engage in a lesson plan that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three...

Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to...

High schoolers discuss the difference between concentration and solubility as well as examine the difference in a hands-on activity. Using water and table salt, they experiment with solubility. They create different concentrations using...

Students make a volcano out of a soda bottle, flower, salt, oil, and more. In this volcanoes lesson plan, students also read about volcanoes.

Students observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.

In this shipping on the Hudson River learning exercise, students record information about types of vessels seen on the Hudson River and respond to the questions that follow about each. Then they identify the Alice Oldendorff which...

Learners identify substances and activities within a household that contribute to water pollution and identify safe cleaning alternatives for commercial cleaning products.

Students construct a still to turn seawater into drinking water. They estimate the cost of distilling it. They investigate ways to make the conversion more efficient. They track the source of their home drinking water and make a map of...

Young scholars investigate the different organisms found in the Great Salt Lake. They collect water samples in order to create an environment that replicates the lake and observe the organisms in a close to natural environment. The...

Eighth graders examine what materials cause water hardness and the relative measure of water hardness in a two part lab activity. In part one, 8th graders add an assigned soap test solution to eleven different test tube solutions in...

Students are able to tell the difference between brackish and salt water. They also are able to distinguish water qualities specific to each type of water. Students answer various questions about all types of water.

Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.

Dilute sulphuric acid is used to oxidize manganate (VII) into manganese (II) and water. Step-by-step procedures are outlined on the activity as well as calculations for junior chemists to perform in their science journals. This...

Young schoolers explore the concept of linear regression. They determine the mass and density of salt water. Pupils add salt to water and record the density as salinity increases, and perform a linear regression on the data to model the...

Students conduct an experiment to show how water gets contaminated through neighborhood runoffs.

In this conductivity learning exercise, students answer post lab questions about substances that transferred electrons resulting in electricity flowing through the conductivity leads use to test each substance.

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...
